Over the last decades, research has shown that selenium plays a critical role in the organism of pigs, especially when the animals are facing stressful events such as weaning, farrowing, and heat stress. However, there are still some misunderstandings about the benefits of selenium and its proper usage, since high levels of the substance in diets can lead to toxicity. In this episode, I have a great conversation with Dr. Darlene Bloxham, a specialist on the subject. She digs into the main questions that arise when it comes to selenium supplementation, including the main differences between selenium sources, the limitations levels, and the ways to supplement it in different production phases, among others.

"Selenium is more effective when supplemented before stress. When you supplement it during stress, it does not accumulate in tissues as rapidly as it could otherwise." - Dr. Darlene Bloxham
